A loose diamond is a diamond that has been polished before being set in a ring or necklace.Because you can check the shine, cut, and transparency of the entire stone, including the parts that are hidden by the frame, it is chosen by those who want to focus their budget on quality, and those who want to make it into jewelry of their choice later.

The loose diamonds sold by Selby come with a certificate of authenticity from GIA (Gemological Institute of America) or Central Gem Laboratory (CGL).GIA is the world's most authoritative appraisal agency in the United States, and CGL is one of the largest appraisal agencies in Japan, both of which use internationally reliable evaluation standards. In addition to the 4Cs of color, clarity, cut, and carat, the evaluation of fluorescence is also specified.

Selby has a direct trade route with overseas polishing companies and dealers that we have built up over many years, and we import loose diamonds directly without going through purchasing agents or middlemen.Since multiple intermediate margins that occur during the distribution stage are reduced, we are able to offer products at significantly lower prices than the general domestic distribution price.

First-hand diamonds refer to new, primary distribution diamonds that are purchased directly from a polishing factory and have never been distributed through general distribution channels.Most of the loose items on the market are ``second-hand'' items that have once been in someone's hands and then recirculated through auctions or inter-vendor transactions, but Selby deals with primary distribution items that have a clean distribution history.

Loose items sold through auctions have a complicated distribution history, with some being recut and repolished, and others having unclear provenance.Selby'sDirect import x first handhas a simple and traceable route from its place of origin to the polishing factory and then to Selby, so its quality, condition, and provenance are clear.

It has a wide variety of uses, such as an engagement ring for a surprise proposal, a wedding anniversary gift, a reward for yourself at a turning point, and a collection with an eye on wealth.Recently, there has been an increase in the number of proposal styles that involve giving a loose ring instead of a finished ring.

All products come with a GIA or CGL certificate, allowing you to objectively check the 4Cs (color, clarity, cut, and carat).If you have any questions, please feel free to contact us via chat, LINE, or in-store.

Type 2a diamonds are extremely rare, highest purity natural diamonds that contain almost no nitrogen and account for approximately 1-2% of all diamonds produced on earth.Selby also sells loose stones with Type 2a certification from the Central Gem Research Institute, which is an official document based on sorting PL analysis (color factor testing). We have set up a system where you can always confirm with an official document from an appraisal agency, regardless of the myth that "Type 2a does not emit fluorescence."

Loose diamonds that come with a GIA certificate will be delivered set in a genuine GIA loose case.

GIA's globally trusted logo cases are perfect for keeping loose items safe and secure. Since the item arrives as a "full set" including the certificate of authenticity and case, it is very popular as a collection or as a gift.
